Adenosine triphosphate, abbreviated ATP, is an organic molecule that supplies energy for all cellular activities in plants, animals, and lower organisms. These molecules capture the stored chemical energy of digested foods and later release it for various cellular processes. Such processes include transport, muscle contraction, nerve impulse propagation, phosphorylation, and synthesis. Thus, it is known as the energy currency of the cell. It also acts as the phosphate donor and the signaling molecule inside the cell....

Cellular respiration is the process by which cells release energy by breaking down glucose molecules. It is broadly categorized into two types: aerobic and anaerobic. What are Aerobic and Anaerobic Respiration Aerobic respiration is the process through which cells break down the glucose molecule to convert its stored biochemical energy into energy-coin Adenosine triphosphate (ATP) in the presence of oxygen. This type of respiration is the primary energy-yielding process of all living beings, providing all the energy to maintain life....

Conjugation is one of the three primary ways of transferring and exchanging genetic material (DNA) between bacteria. The other two are transduction and transformation. It is a mode of sexual reproduction in bacteria. Principle It involves transferring plasmid, other self-transmissible DNA, and sometimes chromosomal DNA from one bacterial cell to the other through direct contact. Thus, one bacterium acts as a donor, and the other serves as the recipient. The plasmid that is transferred is called F-plasmid (F for fertility factor)....

A concentration gradient is a phenomenon where the concentration of particles is higher in one area compared to another. As physics dictates, particles travel from the higher to a lower concentration region during passive transport. Generally, a gradient is how much something changes when that something moves from one region to another. Therefore, concentration gradient refers to how much the concentration changes when something moves from one region to another. In biology, concentration gradient refers to the gradual change in a solute’s concentration in a solution as a function of the distance the molecules traverse....

Diamagnetism is a property exhibited by certain materials, known as diamagnetic materials, that cause them to create a weak magnetic field in the opposite direction when placed in an external magnetic field. It results in the material being repelled by the magnetic field rather than attracted to it, as with paramagnetic and ferromagnetic materials. What Causes Diamagnetism Diamagnetism is a property exhibited by certain atoms, elements, and molecules due to the orbital motion of electrons....

Just like animals have skin, the outermost layers of leaves, flowers, roots, and stems of plants are covered by a layer of tightly packed cells called the epidermis . The cells that form the epidermis are called epidermal cells. The epidermis is a part of the dermal tissue system, acting as the first line of defense against any physical damage and microbial infection. Structure: What is Epidermis Made of Plant epidermis consists of four types of cells: 1) pavement cells, 2) guard cells, 3) trichomes, and 4) cuticles....

The Hall effect occurs when a magnetic field is applied at a right angle to an electric current flowing through a conductor. As a result, a voltage is created across the conductor, perpendicular to both the electric current and the magnetic field. This phenomenon demonstrates how electric and magnetic fields can influence the movement of charged particles in a material. By studying the Hall effect, scientists can learn important information about the charge carriers, such as electrons, within the material....

Hurricanes are cyclones that form over the Atlantic or the eastern Pacific Ocean. They are called typhoons or tropical cyclones in other parts of the world. All tropical cyclones form in the same way that typically requires the same hostile conditions causing devastating consequences when they hit land surfaces. Most hurricanes take around a week to form. However, some are found to have developed within 1-2 days, and a few can take about a month if sufficient water vapor is not present....

A phylogenetic tree, also called an evolutionary tree or phylogeny, represents the evolutionary descent of organisms or genes from their common ancestors. The tree’s root represents the ancestral lineage or taxa, while the tip shows its descendants. During speciation, the tree branches out to form two or more daughter lineages. Scientists who study phylogeny find patterns of shared ancestry between lineages. They are built based on hypotheses supported by facts. Most modern classification systems use phylogenetics to develop relationships among unknown organisms....

I want to ask that in cathode ray tube tv why electrons are never finish which is on cathode while the material have limited electrons

A cold front occurs when a mass of cold, dense air moves into an area of relatively warm, light air, forcing the warm air to rise. Depending on the season, this can lead to noticeable weather changes, such as a drop in temperature, increased cloud formation, and precipitation, such as rain, thunderstorms, or even snow. How Are Cold Fronts Represented on Weather Maps Cold fronts are marked with a blue line and blue triangles pointing in the direction in which the front is moving....

Gene expression is a series of steps by which information encoded in genes creates functional products, such as RNA or proteins. It is a fundamental process that plays a crucial role in all living organisms’ development, functioning, and regulation. Gene expression is the cell’s way of managing the amount and timing of the products created by our genes. This control is crucial because it allows cells to produce the necessary gene products exactly when needed, allowing cells to adapt to a changing environment, respond to signals, and handle damage and other triggers....

Golgi apparatus, also named as Golgi complex, or Golgi body, is a series of flattened, stacked, membrane-bound cell organelle found in all animal and plant cells. It receives molecules, changes them, and then categorizes and addresses them for transport to different cell parts. Golgi is thus analogous to the post office. Due to its relatively large size, the Golgi apparatus was one of the first organelles discovered. In 1897, Italian scientist Camillo Golgi first identified the Golgi apparatus....

Like every star, the sun is a celestial body containing an enormous ball of extremely hot gases that powers the entire universe. The sun is the largest object of our solar system, making up over 99.8% of its total mass. What is the Sun Made of About 70% of the sun’s mass is hydrogen, and another 28% is helium. Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of many other elements such as neon, iron, silicon, magnesium and sulfur....

Adaptations in plants are special features that help a plant survive and reproduce in its environment. These features help plants thrive in different conditions, such as temperature, light, water, soil, and the presence of other organisms. These adaptations may make it easier for plants to survive in one environment but harder to live in another. Plants can develop adaptations over time through evolution. Some of these adaptations are inherited and passed down from one generation to the next, while others are acquired based on the plant’s experiences....

A rotational motion, also known as rotatory motion, is a type of motion in which all points of a rigid body maintain a constant distance from an imaginary axis and rotate in circular paths about a common axis with a common velocity. An object can undergo translational and rotational motion at the same time. Examples Earth rotating about its axis Subatomic particles rotating in a cyclotron A skater exhibiting rotation during her routine A wheel rolling down a hill A football spinning in its trajectory A phonograph’s turntable rotating about a pin A potter’s wheel rotating about its center The following are examples of rotational motion, although they may not seem so....

Seeds are the unit of reproduction in all flowering plants, which give rise to new plants. In some plants, such as walnuts and groundnuts, they act as a source of stored food. Before they can develop into a new plant, seeds need to leave the seed pod. If all the seeds land underneath the parent plant, they might not get enough sunlight, water, and nutrients to germinate. Since plants do not perform the physical movement to take their seeds to another place, there are ways to transport them....

The taiga, also known as the boreal forest, is one of the world’s largest biomes (the largest terrestrial biome) in the sub-arctic region (lies just south of the Arctic Circle), stretching across northern regions of North America, Europe, and Asia. It is characterized by harsh winters, short growing seasons, and nutrient-poor soil. The taiga biome spans regions like Alaska, Canada, Scandinavia, and Siberia. In Russia, the taiga covers an immense area, stretching approximately 5,800 kilometers (3,600 miles) from the Pacific Ocean to the Ural Mountains....
